无法使用毕加索加载 openweatherIcon

Question

I am trying to use the openweather API for my app, and when I try to load the icons, I am not able to do so for some reasons.

This is my mainActivity code that I'm trying to implement so that later on I can try it where I really require it.

    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val layout = findViewById<ConstraintLayout>(R.id.Rlayout)
        val eTime = currentTimeMillis()
        val format = SimpleDateFormat("HH", Locale.getDefault())
        val time = format.format(eTime).toInt()

        if(time in 6..11) {
            layout.setBackgroundResource(R.drawable.gradientmorning)
        } else if (time in 12..18) {
            layout.setBackgroundResource(R.drawable.gradientnoon)
        } else if (time > 18 || time < 6) {
            layout.setBackgroundResource(R.drawable.gradientnight)
        }

        context = applicationContext
        mRequest = Singleton.getInstance(this)
        progressBar = findViewById(R.id.loader)

        dailyRV.layoutManager = LinearLayoutManager(this)                      // dailyForecastAdapter
        dailyAdapter = DailyInfoAdapter()
        dailyRV.adapter = dailyAdapter

        hourlyRV.layoutManager = LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)       //hourlyAdapter
        hourlyAdapter = HourlyInfoAdapter()
        hourlyRV.adapter = hourlyAdapter

        locationVariable = LocationServices.getFusedLocationProviderClient(this)
        getCLocation(context,mRequest)
        progressBar.visibility = View.VISIBLE
        
        Picasso.get().load("http://openweathermap.org/img/wn/04d@2x.png").into(otherImg)
    }

Any reasons as to why the image isn't being displayed at all.

Answer 1

I am using Glide and I add a callback to see what is the exception

the stacktrace print Caused by: java.io.IOException: Cleartext HTTP traffic to openweathermap.org not permitted . So I added android:usesCleartextTraffic="true" to application in AndroidManifest and it works now.

Answer 2

Try adding size for an image you are trying to display. Like this:

Picasso.get()
            .load("http://openweathermap.org/img/wn/04d@2x.png")
            .resize(255,255)
            .centerCrop()
            .into(otherImg);

Answer 3

Open weathermap supports https . So it's recommended to use https in url. From android pie, http urls not permitted directly. You have to use https or if https is not supported, you should add cleartexttraffic flag or xml network config for particular domain in AndroidManifest.xml

Picasso.get().load("https://openweathermap.org/img/wn/04d@2x.png").into(otherImg)
